Description

Technical Field

[0001] This utility model relates to the field of support technology, and in particular to a support. Background Technology

[0002] The sliding assembly is the driving component of an automatically deployable support leg. It typically includes a mounting sleeve, a sleeve, a limiting sleeve, and an elastic element that slide onto the support rod. The support rod of the support leg has a limiting block. One end of the sleeve is connected to the mounting sleeve, and the inner wall of the other end has a raised edge to create a limiting position at both ends of the sleeve. The limiting sleeve and the elastic element are housed within the sleeve, with the elastic element sandwiched between the limiting sleeve and the raised edge. In the retracted state, the sleeve, carrying the limiting sleeve and the elastic element, slides towards the limiting block, compressing the elastic element. After the support leg is unlocked, the elastic element releases energy, pushing the sliding assembly away from the limiting block, causing the leg to unfold.

[0003] The drawback of the existing technology is that the elastic element is simply clamped between the limiting sleeve and the flange. The elastic element is prone to swaying during compression and energy release, which leads to the instability of the sliding component. Utility Model Content

[0004] This utility model provides a bracket to solve the problem that the elastic element in the sliding assembly is prone to swaying, resulting in unstable sliding of the sliding assembly.

[0005] This utility model discloses a bracket, which includes a support rod with a limiting block protruding from its outer wall; a fixed seat fixedly disposed at the end of the support rod away from the limiting block; and a sliding assembly including a sliding seat, a limiting sleeve, a first elastic element, and a sleeve. The sliding seat, the limiting sleeve, and the first elastic element are slidably sleeved on the support rod. The sliding seat has a limiting portion, and the sleeve is sleeved outside the limiting portion, the limiting sleeve, and the first elastic element. The end of the sleeve near the fixed seat has a first limiting groove, the opening of which faces the limiting portion. The limiting sleeve is located between the limiting portion and the first limiting groove. One end of the first elastic element abuts against the limiting sleeve, and the other end accommodates... Within the first limiting groove, and when the bracket is in the retracted state, the limiting block can pass through the limiting part and abut against the limiting block, so that the first elastic element is compressed and stores energy; at least three support foot groups, each support foot group including a support foot and a support rib, one end of the support foot being rotatably connected to the sliding seat, and both ends of the support rib being rotatably connected to the inner wall of the support foot and the fixed seat, respectively; a locking component, which is disposed at the other end of the support foot, is used to lock the other end of the support foot to the fixed seat, so that the bracket remains in the retracted state, or to unlock the other end of the support foot from the fixed seat, so that the first elastic element releases energy, thereby driving the sliding component to slide and the support foot group to unfold.

[0006] Optionally, the sleeve includes a first cylinder, a second cylinder, and a connecting section. The diameter of the second cylinder is smaller than the diameter of the first cylinder. The connecting section connects the first cylinder and the second cylinder at its two ends along the axial direction of the first cylinder, respectively. The connecting section is concave arc-shaped to define the first limiting groove. The end of the first cylinder away from the connecting section is connected to the outer wall of the limiting part. The limiting sleeve and the first elastic element are located inside the first cylinder.

[0007] Optionally, the outer wall of the limiting part is provided with a mounting protrusion, and the end of the first cylinder away from the connecting section is provided with a mounting hole, and the mounting protrusion is detachably installed in the mounting hole.

[0008] Optionally, the limiting sleeve is provided with a second limiting groove on the side facing the first limiting groove, and the end of the first elastic member away from the first limiting groove is accommodated in the second limiting groove.

[0009] Optionally, the inner wall of the limiting part is provided with an avoidance groove, through which the limiting part avoids the limiting block.

[0010] Optionally, the sliding assembly further includes a guide sleeve, which is disposed inside the second cylinder and slidably disposed outside the support rod.

[0011] Optionally, the inner wall of the second cylinder is provided with a buckle hole, and the outer wall of the guide sleeve is provided with a buckle. The buckle is engaged with the buckle hole so that the guide sleeve can be detachably installed in the second cylinder.

[0012] Optionally, the outer wall of the support rod is further provided with a sliding groove, and the inner wall of the guide sleeve is provided with a slider, which is slidably accommodated in the sliding groove.

[0013] Optionally, the guide sleeve has a protruding edge at one end facing the fixed seat, the protruding edge being located outside the second cylinder and abutting against the end wall of the second cylinder.

[0014] Optionally, the locking assembly includes a locking member, a second elastic member, and a control button. The control button is movably mounted on the fixed base. The locking member is slidably connected to the inner wall of the other end of the support leg. The second elastic member is disposed along the length of the support leg on the inner wall of the other end of the support leg. The two ends of the second elastic member are respectively connected to one end of the locking member and the inner wall of the support leg. The locking member has a locking hook portion, and the fixed base has a locking block. In the retracted state, the locking hook portion is locked with the locking block. The control button is used to drive the other end of the locking member to move, so that the locking hook portion disengages from the locking block, and the sliding assembly slides.

[0015] The beneficial effects of the bracket provided in this embodiment of the utility model are as follows: the sliding assembly of the bracket includes a sliding seat, a limiting sleeve, a first elastic element, and a sleeve. The sliding seat, limiting sleeve, and first elastic element are slidably mounted on the support rod. The sliding seat has a limiting portion, and the sleeve is fitted over the limiting portion, limiting sleeve, and first elastic element. The end of the sleeve facing the fixed seat has a first limiting groove, and the limiting sleeve is located between the limiting portion and the second limiting portion. Thus, the limiting portion and the first limiting groove cooperate to limit the limiting sleeve and the first elastic element within the sleeve. The opening of the first limiting groove faces the limiting part. One end of the first elastic member abuts against the limiting sleeve, and the other end is housed in the first limiting groove. When the bracket is in the retracted state, the limiting block can pass through the limiting part and abut against the limiting sleeve, so that the first elastic member is compressed and stores energy. Thus, when the locking component of the bracket unlocks the other end of the support foot from the fixed seat, the first elastic member releases energy, generating a pushing force on the first limiting groove in the direction towards the fixed seat, thereby driving the sliding component to slide and the support foot assembly to unfold. Furthermore, since the opening of the first limiting groove faces the limiting part, this invention can limit the first elastic member axially in the sleeve through the first limiting groove, preventing the first elastic member from swinging during compression and energy release, improving the stability of the sliding component, and ensuring that the energy released by the first elastic member can efficiently act on the sliding component and the support foot assembly, thereby increasing the smoothness of the bracket's retraction and unfolding.

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0032] This utility model embodiment provides a bracket 100, such as Figures 1 to 11As shown, the bracket 100 includes a support rod 1, a fixed base 2, a sliding assembly 3, at least three support foot assemblies 4, and a locking assembly 5. The support rod 1 has a protruding limiting block 111 on its outer wall. The fixed base 2 is fixed to the end of the support rod 1 away from the limiting block 111. The sliding assembly 3 includes a sliding seat 31, a limiting sleeve 32, a first elastic element 33, and a sleeve 34. The sliding seat 31, limiting sleeve 32, and first elastic element 33 are slidably fitted onto the support rod 1. The sliding seat 31 has a limiting portion 311. The sleeve 34 is fitted over the limiting portion 311, the limiting sleeve 32, and the first elastic element 33. The end of the sleeve 34 near the fixed base 2 has a first limiting groove 3431, with the opening of the first limiting groove 3431 facing the limiting portion 311. The limiting sleeve 32 is located between the limiting portion 311 and the first limiting groove 3431. One end of the first elastic element 33 abuts against the limiting sleeve 32. The other end is housed in the first limiting groove 3431, and when the bracket 100 is in the retracted state, the limiting block 111 can pass through the limiting part 311 and abut against the limiting block 111, so that the first elastic element 33 is compressed and stores energy; the support foot assembly 4 includes a support foot 41 and a support rib 42, one end of the support foot 41 is rotatably connected to the sliding seat 31, and both ends of the support rib 42 are rotatably connected to the inner wall of the support foot 41 and the fixed seat 2 respectively; the locking component 5 is provided at the other end of the support foot 41, for locking the other end of the support foot 41 to the fixed seat 2 so that the bracket 100 remains in the retracted state, or for unlocking the other end of the support foot 41 from the fixed seat 2, so that the first elastic element 33 releases energy, thereby driving the sliding component 3 to slide and the support foot assembly 4 to unfold.

[0033] Specifically, the sliding seat 31, the limiting sleeve 32, and the first elastic member 33 are slidably sleeved on the support rod 1. The sliding seat 31 is provided with a limiting part 311, and the sleeve 34 is sleeved on the outside of the limiting part 311, the limiting sleeve 32, and the first elastic member 33. The end of the sleeve 34 facing the fixed seat 2 is provided with a first limiting groove 3431. The limiting sleeve 32 is located between the limiting part 311 and the second limiting part 311. Thus, the limiting part 311 and the first limiting groove 3431 cooperate to limit the limiting sleeve 32 and the first elastic member 33 within the sleeve 34.

[0034] Furthermore, the opening of the first limiting groove 3431 faces the limiting part 311. One end of the first elastic member 33 abuts against the limiting sleeve 32, and the other end is accommodated in the first limiting groove 3431. When the bracket 100 is in the retracted state, the limiting block 111 can pass through the limiting part 311 and abut against the limiting sleeve 32, so that the first elastic member 33 can be compressed and stored. Thus, when the locking component 5 of the bracket 100 unlocks the other end of the support leg 41 and disengages from the fixed base 2, the first elastic member 33 can release energy to generate a pushing force acting on the first limiting groove 3431 in the direction toward the fixed base 2, thereby driving the entire sliding component 3 to slide and each support leg group 4 to automatically unfold for support use. Since the opening of the first limiting groove 3431 faces the limiting part 311, this utility model can limit the first elastic member 33 in the axial direction of the sleeve 34 through the first limiting groove 3431, prevent the first elastic member 33 from swinging during compression and energy release, improve the sliding stability of the sliding assembly 3, and ensure that the energy released by the first elastic member 33 can be efficiently applied to the sliding assembly 3 and the support foot assembly 4, thereby increasing the smoothness of the bracket 100's folding and unfolding.

[0035] More specifically, such as Figure 3 As shown, the support leg assembly 4 includes a support leg 41 and a support rib 42. One end of the support leg 41 is rotatably connected to the sliding seat 31, and both ends of the support rib 42 are rotatably connected to the inner wall of the support leg 41 and the fixed seat 2, respectively. The locking component 5 is located at the other end of the support leg 41. Thus, the support leg 41, the support rib 42, and the sliding component 3 can be linked together, so that the support leg 41 and the support rib 42 can be retracted outside the wall of the support rod 1 or extended to support an object.

[0036] Specifically, when the bracket 100 needs to be stored, the sliding seat 31 can be pushed towards the limiting block 111, thereby moving the entire sliding assembly 3 and each support leg group 4. During the sliding process, the support legs 41 and the support ribs 42 can gradually retract to the outside of the support rod 1. When the limiting block 111 passes through the limiting part 311 of the sliding seat 31 and abuts against the limiting sleeve 32, as the sliding seat 31 continues to move, the first limiting groove 3431 of the sliding seat 31 can gradually approach the limiting block 111, thereby causing the first elastic element 33 to be compressed and store energy. Finally, the other end of the support leg 41 can be locked to the fixed seat 2 by the locking assembly 5, thereby fixing the sliding assembly 3, so that the first elastic element 33 can remain in a compressed state, and the support legs 41 and the support ribs 42 can be stably retracted to the outside of the support rod 1. Furthermore, when the bracket 100 needs to be unfolded, the locking component 5 can be unlocked, allowing the other end of the support leg 41 to disengage from the fixed base 2. This releases energy into the first elastic element 33, generating a pushing force on the first limiting groove 3431 in the direction toward the fixed base 2. This causes the entire sliding component 3 to slide and each support leg group 4 to unfold automatically for support. The first elastic element 33 is a spring.

[0037] It is worth mentioning that, such as Figure 2 As shown, in one embodiment, the support rod 1 includes a plurality of sequentially nested support rod segments 11, and the plurality of support rod segments 11 are telescopically configurable, thereby enabling the support rod 1 to adjust its support height. Understandably, the fixed base 2, sliding assembly 3, limiting block 111, support foot assembly 4, and locking assembly 5 are all disposed outside the outermost support rod segment 11.

[0038] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 3 to 8 As shown, the sleeve 34 includes a first cylindrical body 341, a second cylindrical body 342, and a connecting section 343. The diameter of the second cylindrical body 342 is smaller than the diameter of the first cylindrical body 341. The connecting section 343 connects the first cylindrical body 341 and the second cylindrical body 342 at both ends of the first cylindrical body 341 in the axial direction, and the connecting section 343 is concave arc-shaped to define the first limiting groove 3431. The end of the first cylindrical body 341 away from the connecting section 343 is connected to the outer wall of the limiting part 311. The limiting sleeve 32 and the first elastic member 33 are located inside the first cylindrical body 341.

[0039] Specifically, the diameter of the second cylinder 342 is smaller than the diameter of the first cylinder 341. The connecting section 343 connects the first cylinder 341 and the second cylinder 342 at their respective axial ends of the first cylinder 341, and the connecting section 343 is concave arc-shaped, thereby directly defining the first limiting groove 3431. Furthermore, with the above structure, the sleeve 34 can be manufactured by reducing the diameter of a tube near its end using a tube-shrinking process, directly forming the concave arc-shaped connecting section 343 and the second cylinder 342 at the end of the tube. This ensures that the first cylinder 341, the second cylinder 342, and the connecting section 343 are integrally formed, increasing the stability of the first limiting groove 3431. On the other hand, it simplifies the processing steps of the sleeve 34, helping to improve the production efficiency of the sleeve 34, reduce material waste, and lower production costs.

[0040] It is worth mentioning that the sleeve 34 can be made of metal or plastic. For example, the sleeve 34 is made of stainless steel or aluminum alloy. This effectively increases the structural strength of the sleeve 34 and the first limiting groove 3431, preventing the first limiting groove 3431 from deforming under the force of the first elastic member 33, thus improving the reliability and service life of the entire sleeve 34. On the other hand, it effectively increases the rust resistance of the sleeve 34, enabling it to maintain good performance in various environments for a long time, reducing the frequency of maintenance and replacement.

[0041] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 7 to 9 As shown, the outer wall of the limiting part is provided with a mounting protrusion, and the end of the first cylinder away from the connecting section is provided with a mounting hole. The mounting protrusion is detachably installed in the mounting hole.

[0042] Specifically, the outer wall of the limiting part 311 is provided with a mounting protrusion 3111, and the end of the first cylinder 341 away from the connecting section 343 is provided with a mounting hole 3411. The mounting protrusion 3111 cooperates with the mounting hole 3411 to install and fix the sleeve 32 on the limiting part 311 of the sliding seat 31, so that the limiting part 311 and the first limiting groove 3431 on the connecting section 343 cooperate to accommodate the first elastic member 33 and the limiting sleeve 32 in the first cylinder 341, ensuring the stability of the entire sliding assembly 3 during operation. Moreover, the mounting protrusion 3111 is detachably installed in the mounting hole 3411, thereby facilitating quick assembly and disassembly between the sliding seat 31, the limiting sleeve 32, the first elastic member 33, and the sleeve 34.

[0043] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 5 to 7As shown, the limiting sleeve 32 has a second limiting groove 321 on the side facing the first limiting groove 3431, and the end of the first elastic member 33 away from the first limiting groove 3431 is accommodated in the second limiting groove 321.

[0044] Specifically, the limiting sleeve 32 is provided with a second limiting groove 321 on the side facing the first limiting groove 3431. The end of the first elastic member 33 away from the first limiting groove 3431 is accommodated in the second limiting groove 321. Thus, the second limiting groove 321 can cooperate with the first limiting groove 3431 to simultaneously limit both ends of the first elastic member 33, forming a double limiting effect. This prevents the first elastic member 33 from swinging in the axial direction of the sleeve 34 during compression and energy release, thereby improving the sliding stability of the sliding assembly 3.

[0045] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figure 3 , Figure 5 and Figure 7 As shown, the inner wall of the limiting part 311 is provided with a relief groove 3111, and the limiting part 311 avoids the limiting block 111 through the relief groove 3111.

[0046] Specifically, the inner wall of the limiting part 311 is provided with an avoidance groove 3111. The limiting part 311 avoids the limiting block 111 through the avoidance groove 3111. Thus, in the retracted state, the limiting block 111 can pass through the limiting part 311 and abut against the limiting sleeve 32, so that the first elastic member 33 is compressed and stores energy. After the other end of the support foot 41 is unlocked and disengaged from the fixed seat 2, the sliding seat 31 can avoid the limiting block 111, thereby ensuring that the entire sliding assembly 3 can slide towards the fixed seat 2 under the drive of the first elastic member 33, so as to drive the support foot 41 and the support rib 42 to automatically unfold.

[0047] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 6 to 8 As shown, the sliding assembly 3 also includes a guide sleeve 35, which is disposed inside the second cylinder 342 and is slidably disposed outside the support rod 1.

[0048] Specifically, the guide sleeve 35 is located inside the second cylinder 342 and is slidably sleeved outside the support rod 1. During the storage and unfolding process, the guide sleeve 35 can guide the entire sliding assembly 3 to slide up and down along the support rod 1, thereby improving the smoothness of the sliding assembly 3 sliding along the support rod 1.

[0049] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figure 7 , Figure 8 and Figure 10As shown, the inner wall of the second cylinder 342 is provided with a buckle hole 3421, and the outer wall of the guide sleeve 35 is provided with a buckle 351. The buckle 351 is fastened to the buckle hole 3421 so that the guide sleeve 35 can be detachably installed in the second cylinder 342.

[0050] Specifically, the inner wall of the second cylinder 342 is provided with a buckle hole 3421, and the outer wall of the guide sleeve 35 is provided with a buckle 351. The buckle 351 is fastened to the buckle hole 3421. Through the cooperation of the buckle 351 and the buckle hole 3421, the guide sleeve 35 can be conveniently installed in the second cylinder 342, and the guide sleeve 35 can be easily disassembled and replaced.

[0051] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figure 4 and Figure 10 As shown, the outer wall of the support rod 1 is also provided with a sliding groove 112, and the inner wall of the guide sleeve 35 is provided with a slider 353, which can be slidably accommodated in the sliding groove 112.

[0052] Specifically, the outer wall of the support rod 1 is provided with a groove 112, and the inner wall of the guide sleeve 35 is provided with a slider 353, which is slidably accommodated in the groove 112. Thus, through the cooperation of the slider 353 and the groove 112, the guide sleeve 35 can provide a more precise guiding function, guiding the sliding component 3 to slide along the groove 112 of the support rod 1, effectively improving the smoothness and stability of the sliding component 3.

[0053] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figure 6 , Figure 7 and Figure 10 As shown, the guide sleeve 35 has a protruding edge 352 at one end facing the fixed seat 2. The protruding edge 352 is located outside the second cylinder 342 and abuts against the end wall of the second cylinder 342.

[0054] Specifically, the guide sleeve 35 has a protruding edge 352 at one end facing the fixed seat 2. The protruding edge 352 is located outside the second cylinder 342 and abuts against the end wall of the second cylinder 342. Thus, the protruding edge 352 can form a protective layer on the outside of the end wall of the second cylinder 342 facing the fixed seat 2. When the sliding component 3 slides to the position of the fixed seat 2, the end wall can play a buffering role, reduce the collision force of the second cylinder 342 and the fixed seat 2, and protect the second cylinder 342.

[0055] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figure 3 and Figure 11As shown, the locking assembly 5 includes a locking member 51, a second elastic member 52, and a control button 53. The control button 53 is movably mounted on the fixed base 2. The locking member 51 is slidably connected to the inner wall of the other end of the support leg 41. The second elastic member 52 is disposed along the length of the support leg 41 on the inner wall of the other end of the support leg 41. The two ends of the second elastic member 52 are respectively connected to one end of the locking member 51 and the inner wall of the support leg 41. The locking member 51 is provided with a locking hook portion 511, and the fixed base 2 is provided with a locking block 21. In the retracted state, the locking hook portion 511 is locked with the locking block 21. The control button 53 is used to drive the other end of the locking member 51 to move so that the locking hook portion 511 disengages from the locking block 21 and the sliding assembly 3 slides.

[0056] Specifically, the locking member 51 is slidably connected to the inner wall of the other end of the support leg 41. The locking member 51 is provided with a locking hook 511, and the fixed base 2 is provided with a locking block 21. When the locking hook 511 and the locking block 21 are locked, each support leg 41 can be fixed on the fixed base 2, so that the support leg 41 and the support rib can be folded up outside the wall of the support rod 1 for easy storage. The control button 53 is movably set on the fixed base 2. The locking member 51 is slidably connected to the inner wall of the other end of the support leg 41. The second elastic member 52 is provided along the length direction of the support leg 41 on the inner wall of the other end of the support leg 41. The two ends of the second elastic member 52 are respectively connected to one end of the locking member 51 and the inner wall of the support leg 41. Thus, the user only needs to press the control button 53 to easily and conveniently release the locking member 51 from the fixed base 2, so that the support leg assembly 4 is released from the fixed position, so that the sliding component 3 can slide towards the fixed base 2 under the action of the first elastic member 33, thereby driving the support leg 41 and the support rib 42 to unfold for support. Specifically, when the control button 53 is pressed, the control button 53 moves along the fixed base 2 and drives the other end of the locking member 51 to move along the inner wall of the support foot 41, so that the locking hook part 511 of the locking member 51 disengages from the locking block 21 of the fixed base 2, thereby allowing the support foot 41 to disengage from the fixed base 2.

[0057] Furthermore, since the second elastic element 52 is disposed on the inner wall of the other end of the support foot 41 along the length direction of the support foot 41, and the two ends of the second elastic element 52 are respectively connected to one end of the locking element 51 and the inner wall of the support foot 41, the second elastic element 52 can drive the locking element 51 to automatically reset after the locking hook part 511 disengages from the locking block 21. The second elastic element 52 is a spring.

[0058] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
